What is BLEND 300 (Trenbolone Acetate 100mg + Drostanolone Propionate 100mg + Testosterone Propionate 100mg)?
BLEND 300 is a short-ester triple-compound research preparation combining Trenbolone Acetate 100mg/mL, Drostanolone Propionate 100mg/mL, and Testosterone Propionate 100mg/mL in a single oil-based injectable solution. All three esters share a fast-acting short-ester profile, making this a standardised multi-compound pharmacokinetic research formulation. Research use only.
Research Applications
Multi-Compound Pharmacokinetics
Simultaneous serum profiling of three anabolic compounds — peak, half-life, and clearance
Androgen Receptor Binding Studies
Comparative AR affinity: trenbolone (~3×), drostanolone (~3×), testosterone (reference)
Short-Ester Release Kinetics
Rapid ester hydrolysis, Cmax timing, AUC for propionate/acetate esters
SHBG Displacement Research
Free androgen availability — drostanolone SHBG competition models
Anabolic/Androgenic Ratio Research
Tissue-selective androgenic index studies across three distinct androgen scaffolds
